I am using a Dell Vostro 1520 running primarily Windows 7 x64 Pro. I am trying to become more acquainted with Linux and therefore created a dual boot with Fedora 14 X64 from a live USB. Initially I had problems with the wireless hardware not being recognized by Fedora, but that was fixed by updating the firmware. I am currently using

Wifi Card:Broadcom Corporation BCM4312 802.11b/g
Firmware version A08

Updating the firmware fixed the initial problem (because the firmware was telling fedora that the wifi card was turned off) but when I did this, it created the exact opposite problem in windows. Now I have a Fedora partition which can access the web via the wifi, and the Windows installation will not even begin to recognize networks. I don't even know how to approach this at this point, I have everything on Windows, and I feel as though I'm stuck in a stupid loop. Please help, any comments are appreciated. I really don't know what to do.

What I would try first is boot windoze, go into the device manager, remove the card, boot, the system should detect the 'new hardware' and allow windbloze to install the card. You might have to do some configuring to match your netowrk, SSID etc. I would think that will get it going in windoze.

I'm wondering where you saved the firmware? Doing something in linux, I wouldn't expect that to have any effect on windbloze.

I can't remember the exact location, but I think it's under
C:\Windows\Temp\WINPHLASH\1.0.3.5 although there is a separate BIOS partition (I'm not exactly where the default install location is in WINPHLASH)

Secondarily, I think I may have put this thread in the wrong forum. This is because I went to school today and the wifi on windows and Fedora are both working time. This leads me to believe that it may, in fact be a router problem at my house. I will check when I return home. In the mean time just awaiting confirmation of suggestion on whether or not I should move this thread.

Oh yes, Windows and Linux can influence each other. I'm currently having the problem that after using windows on my PC, X will crash in Ubuntu 10.04. I need to remove xorg.conf, reboot, copy xorg.conf back and reboot.

The problem here is that after a shutdown in windows the HW is left in a certain state. I must still try a power cycle to check if it will solve the issue.

Previous Conception Confirmed:

Today when I went home, I booted into Fedora as well as Windows, and both had successful wifi access. I don't know how it was done because it wasn't working before. Anyway, than you for all of your help. I really appreciate it. I apologize for not realizing the fix earlier, and I'm now on my way to becoming a fulltime linux user for the purposes of programming in Python.
